A child bone fracture or a pediatric fracture is a medical condition in which a bone of a child (a person younger than the age of 18) is cracked or broken. [1] About 15% of all injuries in children are fracture injuries. [2] Bone fractures in children are different from adult bone fractures because a child's bones are still growing. Also, more ...
For children and adolescents, there are three main categories of fracture: buckle (torus) fractures, greenstick fractures, and complete (or off-ended) fractures. [4] Buckle fractures are an incomplete break in the bone that involves the cortex (outside) of the bone. Buckle fractures are stable and are the most common type. [4]
When a bone fractures, the fragments lose their alignment in the form of displacement or angulation. For the fractured bone to heal without any deformity the bony fragments must be re-aligned to their normal anatomical position. Orthopedic surgery attempts to recreate the normal anatomy of the fractured bone by reduction of the displacement.
Age, bone type, drug therapy and pre-existing bone pathology are factors that affect healing. The role of bone healing is to produce new bone without a scar as seen in other tissues which would be a structural weakness or deformity. [2] The process of the entire regeneration of the bone can depend on the angle of dislocation or fracture.
Treatment of greenstick fractures typically begins with reduction (realigning bone segments) if the bone portions on either side of the fracture form an angle, as opposed to being straight and already aligned. This is followed by the application of a well-molded cast that immobilizes the joints above and below the fracture site.
Autologous bone graft is the "gold standard" treatment and possesses osteogenic, osteoinductive, and osteoconductive properties, although only a limited sample can be taken and there is a high risk of side effects. [11] Bone graft substitutes. Inorganic bone substitutes may be used to complement or replace autologous bone grafting.
A skull fracture is a break in one or more of the eight bones that form the cranial portion of the skull, usually occurring as a result of blunt force trauma.If the force of the impact is excessive, the bone may fracture at or near the site of the impact and cause damage to the underlying structures within the skull such as the membranes, blood vessels, and brain.
Bones are constantly attempting to remodel and repair themselves, especially during a sport where extraordinary stress is applied to the bone. Over time, if enough stress is placed on the bone that it exhausts the capacity of the bone to remodel, a weakened site—a stress fracture—may appear on the bone. The fracture does not appear suddenly.
